I found a very good uploader script here: http://valums.com/ajax-upload/
However, I want to be able to limit to total upload size of all the files. It lets me restrict the individual sizes, but is there a way to limit the total of all the sizes? For example, if I restrict the individual max size to 10MB, I could upload 20 9.8 MB files. I want to be able to let the files be any size they want as long as the total size of all the files don't go higher than 10 MB. Is this possible?
